Changes since v6 [1]: - The CXL Vendor ID assigned by the PCI SIG is 1e98h and replaces the 8086h value used in the CXL rev1.1 and prior specifications. (Errata CXL 1.1 sec E27) [1] https://lore.kernel.org/linux-pci/20200420221444.2641935-1-sean.v.kelley@xxxxxxxxxxxxxxx/ This patch series adds support for basic lspci decode of Compute eXpress Link, a new CPU interconnect building upon PCIe. As a foundation for the CXL support it adds separate Designated Vendor-Specific Capability (DVSEC) defines and a cap function so as to align with PCIe r5.0, sec 7.9.6.2 terms and provide available details. It makes use of the DVSEC Vendor ID and DVSEC ID so as to identify a CXL capable device.
